EMERGENCY CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 748,927, dated January5, 1904:. Application filed October 30, 1903 Serial No. 179,173. (Nomodel.)

To all whom it may concern.-

Beit known that we, BRYANT B. CARLISLE and JOHN R. ELDER, citizens of"the United States, residing at 0010 mhus, in the county of Franklin andState of Ohio, have invented a certain new and useful Improvement inEmergency Car-Couplers, of which the following is a specification.

Our invention relates to the improvement of emergency car-couplings, andhas particular relation to the improvement of the c0nstruction set forthin our former application for patent, Serial No. 165,808, filed July 16,1903.

The objects of our present invention are to provide an improvedemergency car-coupler which may be utilized for the purpose ofconnecting cars from which one or more drawbars or coupler-heads havebeen broken or in which the draft-timbers have been pulled out ordisplaced, to provide an improved construction of yoke for embracing thekingbolt ofa car, to so construct our improved coupler as to permit ofsuch lateral movement of its sections as to compensate for the movementof the cars with which our device may be connected, and to produce otherimprovements the details of which will be more fully pointed outhereinafter. These objects we accomplish in the manner illustrated inthe accompanying drawings, in which- Figure 1 is a plan View of ourimproved coupler, and Fig. 2 is a side elevation of the same.

Similar numerals refer to similar parts throughout the several views.

In carrying out our invention we employ an integral yoke-like body 1,the end portions of the parallel arms of which are adapted to beinserted through openingin a transverse bar 2, said yoke-arms being heldfrom voluntary withdrawal from said bar through the medium of pins orkeys 3, which are preferably of the wedge shape shown and which areadapted to'be insertedin openings in the outer end portions of saidyoke-arms. At the center of its length the bar 2 is provided with achanneled lip or lug 4, with which is connected through the medium of avertical and removable pivot-pin 5 therear end of a the cars towardor-from each other.

connecting-bar 6. The forward end of this connecting-bar is likewisepivoted between the jaws 7 of the recessed or bifurcated head of a screwmember 8, the latter having its threaded portion adjustably entering oneend 5 5 of a turn buckle 9. Similarly connected with the opposite end ofsaid turnbuckle is the threaded portion of a screw member 10,corresponding with the member 8 and between the outer end jaws ll ofwhich is pivoted, as prescribed for the bar 6, a forwardly-extending bar12, the latter having formed at its outer end on its upper and lowersides opposing bosses 18, through which and the body of the bar 12 isformed a suitable opening 14.

In utilizing our device the yoke l is first made to embrace theking-bolt of a car which has been injured, after which theforwardlyextending parallel members of the yoke are inserted through.the openings in the bar 2 7c and the pins 3 dropped or driven intoplace. It will be observed that in the formation of the yoke-body l weprovide upper and lower projecting lugs liand l",which when the yoke isin place are designed to respectively engage the body and truck bolstersof the car. The knuckle being removed from the drawbar of the adjoiningcar, the connection of the two cars is made by the insertion of theouter end portion of the bar 12 in the drawbar of said adjoining car,the enlarged end of said bar receiving the usual knuckle-pin to connectit with the draw-bar.

From the description heretofore given it will be seen that we havesimplified the construction of the clam ping-yoke and the partsconnected therewith and that by the intro duction of the pivoted bars 6and 12 a desirable lateral motionmay be attained by the sections formingour coupler, these move- 0 ments of the parts being deemed necessary tocompensate for the slack or movements of It will he understood that suchrotary motion of the parts as may result from the movements of the carswill be attained through the employment of the turnbuckle 9, which, aswill readily be seen, may be also utilized in adjusting our improvedcoupler to various lengths.

Having now fully described our invention, loo

what We claim, and desire to secure by Letters Patent, is

1. In an emergency car-coupler, the combination with a king-bolt clampcomprising an integrally-formed yoke and a cross-bar detachablyconnecting the ends of said yoke, of a coupler-body comprisingjointedly-connected sections one of which is pivotally connected withsaid clamp.

2. In an emergency car-coupler, the combination with a clamp comprisingan integrally-formed yoke and a cross-bar detachably connecting the endsof said yoke, of a coupler-body comprisingjointedly-connected sectionsand an intermediate turnbuckle adjustably connected with two of saidsections, one section of said coupler-bar having a pivotal connectionwith the clamp and another section thereof being adapted to receive acoupling-pin.

3. In an emergency car-coupler, the combination with a clamp adapted toengage a king-bolt, of a turnbuckle and screw members adj ustablyconnected with opposite ends thereof, a bar 6 having a pivotalconnection 1 with one of said screw members and a pivotal connectionwith said clamp and a bar 12 having a pivotal connection with theremaining screw member.

4. In an emergency car-coupler, the combination with a clamp comprisingan integrally-formed yoke-body and a removable cross-piece connectingthe arms of said yoke, said yoke-body having upper and lower projectinglugs, of a coupler-body comprising a turnbuckle, screw membersadjustably connected with opposite ends of said turnbuckle, a jointedconnection between one of said screw members and said clamp and a barpivotally connected with the remaining screw member.
